SUSPENSION MEANS FOR PRIME MOVERS.

.V to the means whereby they are supported by and connected to the partsoperated thereby 'I and it relates particularly to electric motors andt0 means whereby they are supported by andconnected to shafts or othermovable parts. j The object of my invention is to provide novel andimproved means whereby electric motors or ot 1er-prime movers may be re*siliently supported and connected `to shaftsl or other movable parts.

. The propelling motors of electric railway vehicles are usuallysupported at one side, by means of bearings, upon the driving axles towhich they are operatively' connected by speed-changing' gearing,resilient suspern sion means being provided at the other side. In orderthat a motor may be resiliently suported atboth sides, it has beenproposed to oosely surround thel axle with a quill or sleeve and toresiliently mount or support vthe sleeve thereon, the motor being gearedto and supported at one side upon the sleeve; and for the purpose ofrelieving the motor and other parts from the severe shocks and strainsto which` they are usually subjected when the vehicle is suddenly.started and stopped, it has' been proposed further to introduceresilient driving connections between the sleeve and the axle. I proposeto 40 secure the desired result by providing a structure which shall bemore simple, coinpact and practical than those heretofore suggested, andone in which the sleeve, that supports one side of thel motor and isgeared toit, is resiliently supported out of engagement With theinelosed axle by the saine means that affords a driving'connectionbetween it and the axle.

l Figure 1 0f the accompanying drawings is 5u a plan view of a motorthat is supported and connected to the driving axle of an electriclocomotive in accordance with my invention, a portion of the structurebeing broken away for the sake of clearness of illustration,

5i and Fig. 2 is a view, in elevation and in section, on the line II-IIof Fig. 1, of the parts shown therein.

An. axle'l, that may be the driving axle oi Ian electric locomotive orother vehicle and.

that is provided at its ends with driving wheels 2 and 3 havingsets ofannularly arranged chambers 4, is loosely surrounded b v a quill 5having annular flanges or radial arms 6 at its ends and bosses 7, thatproj ect therefrom into the wheel chambers 4. The bosses 7 aresurrounded within'the wheel chambers-by suitable resilient means, suchas'specially formed helical springs` 8, that comprise a plurality ofconvolutions, the adjacent ones of which are eccentric, such a 70spring'forming the subjeotdnatter of a separate application, SerialNo.'291,410, filed by me January 3, 1906. An electric motor 9, wherebythe vehicle is propelled, is provided at one side with bearings .10which, in the present instance, surround and engage the quill insteadol' bearing upon the axle 1, as is usual, and the rotatable member ol'the motor is operatively connected to the quill `5 by means ol" speed-80 reducing gearing 11, or it may be connected thereto by any 'othersuitablemeans. The side oi the motor opposite the bearings 10 is securedto a cross-bar 12, that maybe resiliently supported by any suitablemeans (not shown), or other means may be provided for resilientlysupporting that side ol' the motor.

T he springs 8 servo to introduce resiliency into the connection betweenthe motor and the driving wheels and to thereby reduce the eilect, uponthe motor and other parts, ol' shocks and jars caused by suddenstartingl and stopping olI the vehicle or otherwise, and they alsoAserve to resiliently support the side of the motor Athat is connectedto the drivingl wheels. It will, oll course, be understood that thequill may be resiliently connected to the driving wheels in any othersuitable manner than that which I have here shown and described and thatthe electric motor is only indicative cfa .suitable prime mover or other-device that may be similarly mounted and vofchamhers, a quill orchambers, of ,rounding the mounted thereon having annular sets of aquill or sleeve loosclj,Y suraxle between the wheels and having radialarms or flanges and bosses that project therefrom into the wheelchambers, resilient cushioning means surrouinling the bosses within thechambers, a prime mover on'the sleeve and speed-changing connectionsbetween the prime mover and the quill.

2. 'lhe combination with an axle and wheels mounted thereon havingannular sets sleeve loosel;v surrounding the axle between the wheels andi having radial arms or flanges and'bosses that proect therefrom bossesWithin the chambers and a prime mover having bearings at one sidethereof upon the quill or sleeve and operative o onnections between theprime mover Vand the quill.

3. The combination with an axle, wheels mounted thereon, a quill orsleeve looselj,T surrounding the axle between the wheels and resilientdriving connections .between the quill andeach ofthe wheels, saidconnections serving also to normally support the quill substantiallyconcentric with the axle, ol' a prime mover, bearings at one sidethereol'l on the quill and operative connections between the prime moverand the uill.

4. The combination with an axle, a quill or sleeve looselysurroumling'the same and resilient driving connections between each'into the wheel chambers, resi lent cushioning means surrounding the endofthe quill and the axle said connections serving also to normallysupport the quill out of engagement with the axle, of la prime mover,bearings therefor upon the quill and speed reducin f .I connectionsbetween the prime mover and the quill.

The,combination with an axle, a quill or sleeve looselysurrounding thesame andresilient driving connections between ea ch end of the quill andthe axle said connections serving also to normallxv support the quillout of engagement with the axle, of a d vnavn10-electric machine,bearings therefor upon the quill and speed-reducing connections betweenthe dynamo-eleetric machine and the quill.
